Effect of Vermicompost Dose to K Content in Leaves and Growth of Corn (Zea mays, L) on Ultisol

Abstract

The objectives of this research were to obtain an optimum dose of vermicompost fertilizer to the nutrient levels of K in the leaves, K uptake, and corn growth in ultisols. This research were held in September until November 2018, which has been implemented in green house and the Laboratory of Soil Science, Faculty of Agriculture, University of Bengkulu. The research used Completely Randomized Design (CRD) with a single factor consisting of 7 levels of treatment and three replicates i.e. 0 , 2.5 , 5.0 , 7.5 , 10.0, 12.5, and 15.0 ton ha-1. The results showed that the optimum dose of vermicompost fertilizer 5.71 ton ha-1, resulting in leave K content of 0.59%, 9.5 ton vermicompost ha-1, producing the absorption of K leaves 31 kg ha-1, 9.59 ton vermicompost ha-1, producing a plant height 160.7 cm, 10.2 ton vermicompost ha-1, producing the fresh stover weight 27,561.2 kg ha-1, 98.9 ton vermicompost ha-1, producing the dry stover weight 5,675.5 kg ha-1, and 9.5 tons vermicompost ha-1, producing root dry weight 1,156 kg ha-1.

“…The interaction between compost fertilizer (P2) and compost dose gave the highest dry stover weight of 214.0 g plant -1 ( 14,267 KgHa -1 ) at a compost dose of 20 TonHa -1 . Nurjanah et al [14] obtained The highest weight of dry corn stover was 5,675.5 KgHa -1 with a vermicompost dosage of 9.9 TonHa -1 . Thus, when compared, the dry stover weight of corn plants from this study is 2-3 times higher than the dry stover weight of corn plants from the research results of Nurjanah et al [14].…”

“…According to Nurlaila [13], the highest corn plant height of 195.5 cm was obtained at a vermicompost dose of 13.5 TonHa -1 . [14] obtained the highest corn plant height of 160.7 cm at a vermicompost dose of 9.59 TonHa -1 . Compost fertilizer (P2) at a dose of 10 tonHa -1 provides the highest corn plant height (100.50 cm) [15].…”

“…The interaction between vermicompost fertilizer (P1) and vermicompost dose gave the highest wet stover weight at a dose of 20 TonHa -1 , namely 710.5 gplant -1 or 47,367 KgHa -1 . [14] said that the highest wet stover weight was 27,561 KgHa -1 at a vermicompost fertilizer dose of 10.2 TonHa -1 . When compared between the two, the highest corn plant height from this study is better than the corn plant height obtained by Nurjanah et al [14].…”
